    Alpine Type-R 12" ported or sealed

    I have a my Alpin in a 1 cubic foot box and was wondering if any body knows if it will sound better or louder in a ported box. I had a Preditor 12" in a ported 3 foot ported box and it got louder but more distorted.

    Thanks

    That's a big a** box. hope it will fit. do you think I could use a smaller ported box like 2ft cubed, and do you think it would sound allot better than the sealed box does.

    2 cubes ported.... I'd just stick to a sealed design....

    The Infinity perfect 12 ask for a 1.75 ported box. Is that because it's made for that? Maybe I should of went with the perfect.

    different woofers react differently to different enclosures...

    If space is an issue.. find a low Fs, low Qts woofer...

    The Perfect is almost the same. It is (Fs 23.663, Qts 0.38 Vas 87.5L). So can I use the same box specs (1.75cubic ft).

    the enclosure looks a little boomy to me.. but it'll probably work...

    Course Im **** about enclosures.. so you'll probably be fine with it.. lol

    go with 2 cuft with a 4" round port that is 12 long..
